Description

Transverse cutting shear structure capable of quickly replacing shear blade

Technical Field

The utility model relates to the technical field of strip steel production, in particular to a transverse shearing structure capable of quickly replacing a shearing blade.

Background

The transverse shearing is a key device in the strip steel production line, and is mainly used for transverse cutting of strip steel and cutting of quality defect parts. Because of the frequent use, when the cutting edge wears, it is necessary to replace the cutting edge in time. Shortening the time for changing the cutting edge and facilitating the operation when changing the cutting edge is the development direction of the device.

Some existing transverse shears fasten a cutting edge to a cutter seat through bolts. The shear blade is replaced by stopping the production line, manually disassembling the transverse fastening bolts in a narrow space according to the running direction of the strip steel, translating the shear blade out along the direction of the machine set, and then reloading the new shear blade in the reverse order. In the technology, the tool apron and the shearing blade are fastened by more than ten bolts, and the operation space is limited when the bolts are disassembled, so that the working difficulty is increased. And the shearing blade can only be moved out from the inlet side or the outlet side of the equipment, so that the carrying and the lifting are inconvenient. In addition to the difficulty in operation during blade replacement, the shearing machine with the structure has certain requirements on equipment arrangement before and after the shearing machine, and enough operation space must be reserved.

The existing other transverse shears need to stop the production line, transversely move the whole shear body out of the production line through a translation mechanism, disassemble the shear blade, hoist the new shear blade and replace the whole upper and lower shear blades. And when the device moves out of the production line, the disassembly and hoisting space is sufficient. The structure of the shearing machine is complex, the production line is required to stop, the outermost frame is separated from the middle shearing body structure, and the shearing body structure is translated out of the production line through the translation hydraulic cylinder and the track device. This structure requires space in the workshop. Although there is enough space to replace the cutting edge, the action is complex, and a lot of cutting edge replacement time is still required.

Therefore, the inventor provides a transverse shear structure capable of quickly replacing the shear blade by years of experience and practice in related industries so as to overcome the defects of the prior art.

13. The crosscut shear structure of claim 12, wherein said lower blade carrier chute and said lower telescoping slide are T-shaped or dove tail shaped in cross section.

14. The crosscut shear structure capable of quickly replacing a shear blade according to claim 11, wherein the lower locking cylinder is a disc spring locking hydraulic cylinder, a lower disc spring is arranged between one end of the lower cylinder rod, which is far away from the lower tool holder, and the lower cylinder cover, a lower locking cylinder oil port is arranged at one end of the lower locking cylinder barrel, which is far away from the lower tool holder, and is communicated with a second reversing valve, the second reversing valve is used for feeding oil to the lower cylinder rod to extend so as to loosen the lower tool holder and the lower shear blade, and the second reversing valve is used for returning oil to the lower cylinder rod to retract so as to lock the lower tool holder and the lower shear blade to the lower tool holder.

15. The shear structure of claim 14, wherein said lower locking cylinder is removably connected to said lower locking cylinder block by a locking cylinder positioning structure.
